摘要： A method and an apparatus for biological wastewater treatment that includes a biological selector and a physical selector. The apparatus comprises an internal biological reactor where wastewater and recycled biomass are combined to provide a high substrate and high electron acceptor gradient for generating morphological biomass features that favor granule formation over floc and filament formation, and an external gravimetric or external screen selector operating on the biomass waste stream for collecting and retaining densified biomass aggregates including dense granule selection and for wasting lighter filaments and flocs. In the method and apparatus, particles may be added to provide cores to promote the formation of aggregates encapsulating the seeded particles. The particles may be added as various materials, for example, in the bioreactor, to initiate or seed the formation of a granule, that could then be separated by or integrated with either the external gravimetric or external screen selector. Further, organisms may be selected for biological phosphorus removal, denitrifying methane oxidizers, biological sulfur or sulfide oxidation, methanogenesis.

摘要： A methodology, system and apparatus are provided that include anoxic biofilms to perform partial denitrification and anammox (PdNA) reactions. The PdNA reactions can facilitate process intensification and carbon efficient biological nitrogen removal. The anoxic biofilms can be placed in a pre-anoxic zone or a downstream anoxic zone, where the biofilm and reactions are managed, including using storage compounds, to overcome mass transfer limitations in the biofilm. The methodology, system and apparatus can, when compared to state-of-the art technologies, improve the concentration gradient or reduce mass transfer limitations to facilitate PdNA reactions.

摘要： This disclosure relates to physical selection, deselection or outselection for smaller, less dense, sheared or compressed particles in sludge, wherein the first deselection step occurs at the reactor or at a clarification step, by separately deselecting for such particles and then a second deselection step occurs in an external selector. This double deselection promotes the more efficient removal of slow settling particles, while simultaneously allowing for maintenance of multiple solids residence times for fast and slow growing organisms. The deselection in a clarifier occurs typically at the periphery of the tank or at the surface of a blanket using a positive or negative pressure device. Structures such as slotted or perforated plates, pipes or manifolds can be used to assist in such deselection. Baffles can also be used for such deselection.

摘要： A method and a system as described herein, including a method and system of treating ammonium containing water in a deammonification MBBR process where partial nitritation and anaerobic ammonium oxidation may occur simultaneously in a biofilm, or in an integrated fixed film activated sludge process where partial nitritation takes place in a suspended growth fraction and anaerobic ammonium oxidation occurs in a biofilm. The method and system include controlling airflow to the reactor to achieve a target pH, a target alkalinity, a target specific conductivity, and/or a target ammonium concentration in the reactor or in the effluent.
